The width of the base in a GaAs transistor and in a Si (both npn type) are equal. GaAs works at higher frequency because
- the negative differential mobility in GaAs favours operation at very high frequency
- base transit time is lower in GaAs
- the band gap of GaAs is higher than that of Si
- Si transistor works at higher frequency compared to GaAs
